Yes, obviously it is, that was never in question from my side though. However the question remains how far laws can help with discrimination. As you know racial discrimination is illegal in the USA for some decades now. So how is the situation today? Did those laws fix racism? Sure people can put up discriminatory signs anymore but in fact the USA is still one of the most racist societies on the planet, until this day. So obviously laws can help only to a certain degree. I think laws can help with public and structural/institutional discrimination pretty well but they can not fix individual discrimination. So obviously, there is a limit to how far we can get in fixing this problem just by making more laws. What laws can not change is how people feel and think, only real social development towards more tolerance, based on proper education can do that imo.
